Donesite izvornik u ured.

Yes. Donesite is the imperative form, so it gives an instruction or command: bring.

In this sentence, donesite is:

• 2nd person plural imperative: you all, bring
• also used as the polite/formal singular: please bring (when speaking politely to one person)

So Donesite izvornik u ured. can be said:

• to several people
• or to one person politely

It comes from the verb donijeti / donositi, meaning to bring. Here the form donesite is the perfective-style imperative, which fits a single completed action: bring it (to the office).

It is usually formal/polite when speaking to one person, because Croatian uses the plural form to address someone politely.

So:

• Donesi = informal singular, used with one person you know well
• Donesite = plural or polite singular

That means this sentence sounds appropriate in situations like:

• at an office
• in administration
• in customer service
• in formal instructions

If you wanted to make it even softer, you could add molim or molim vas, for example:

• Molim vas, donesite izvornik u ured.

Izvornik means the original or the original document/original copy.

In everyday Croatian, especially in administrative or office contexts, izvornik often means:

• the original version of a document
• not a photocopy
• not a scan
• not a certified copy unless specifically stated

So in practice, this sentence often means something like:

• Bring the original document to the office.

The noun is masculine.

It is in the accusative case, because it is the direct object of donesite.

However, for masculine inanimate nouns, the accusative singular is often the same as the nominative singular.

So:

• nominative: izvornik
• accusative: izvornik

Because izvornik is inanimate, the form does not change here.

If it were a masculine animate noun, you would usually see a different accusative form.

This is a very important Croatian pattern.

The preposition u can take different cases depending on meaning:

• u + accusative = movement into/to
• u + locative = location in/inside

So:

• u ured = to the office / into the office
• u uredu = in the office

In your sentence, there is movement toward a destination, so Croatian uses the accusative:

• Donesite izvornik u ured. = bring the original to the office

Compare:

• Izvornik je u uredu. = The original is in the office.

Because Croatian does not have articles like a/an/the.

So nouns like izvornik and ured can mean:

• an original / the original
• an office / the office

The exact meaning depends on context.

In this sentence, English naturally uses the because the context usually makes both nouns specific:

• the original
• the office

Croatian leaves that specificity to the situation rather than using an article.

The form donesite is tied to the perfective verb donijeti.

Croatian often works with verb pairs:

• donositi = imperfective, focusing on process, repetition, or general action
• donijeti = perfective, focusing on bringing something as a completed result

In an instruction like this, Croatian commonly uses the perfective imperative because the speaker wants one completed action:

• Bring the original to the office.

That is why donesite fits well here.

By contrast, donosite would come from donositi and would have a different feel, often less natural for a simple one-time instruction.

Yes, Croatian word order is more flexible than English word order.

The basic sentence:

• Donesite izvornik u ured.

Other possible orders can occur, for example:

• Izvornik donesite u ured.
• U ured donesite izvornik.

These alternatives may change the focus or emphasis, but not the core meaning.

For example:

• Izvornik donesite u ured. may emphasize the original
• U ured donesite izvornik. may emphasize to the office

The original version is a very natural neutral order for an instruction.

By itself, it is a straightforward instruction. Whether it sounds rude depends on context and tone.

Croatian imperatives are normal in:

• instructions
• notices
• administrative communication
• workplace directions

Because donesite is the polite/plural form, it is already less blunt than donesi.

Still, if you want to sound softer, Croatian often adds polite expressions such as:

• Molim vas, donesite izvornik u ured.
• Možete li donijeti izvornik u ured?

So the sentence is not automatically rude, but it is more direct than a softened request.

A simple learner-friendly pronunciation is:

• donesite ≈ do-NEH-see-teh

A few helpful notes:

• e is usually pronounced clearly, like e in met, not like the English silent e
• all vowels are pronounced
• Croatian spelling is quite regular, so words are usually pronounced much as they are written

If you say each syllable clearly, you will be understood well:

• do-ne-si-te

Yes, but office is the most common meaning in this kind of sentence.

Ured can refer to:

• an office room
• an office as an institution or department
• an administrative office

So depending on context, u ured could mean:

• to the office room
• to the office department
• to the administrative office

In practical everyday usage, especially with documents, it often means an administrative office or office location where documents are submitted.
